42. What is JDBC

  • JDBC (Java Database Connectivity) provides a standard interface for accessing a relational database from a Java application regardless of where the application is running and where the database is.
  • It provides a way for Java applications to call SQL and PL/SQL.
  • In other words it is a way to execute SQL statements and also call stored database procedures.
  • One important feature of JDBC is location independence. Java programs with database access can be written and deployed as an application or as a Web-based applet.
  • The ease of development, robustness, and security of Java programs makes it a good choice for writing database applications in Java.
  • JDBC consists of a high-level “thin” API and multiple low-level drivers for connecting to different databases.
